Stabbing-preventing insulin needle

Abstract

A stabbing-preventing insulin syringe needle comprises a connecting block, a guide rod and a first sleeve, a conical hole is formed in the top end of the connecting block; a through hole is formed inthe bottom of the conical hole, a needle head is fixedly connected to the inner wall of the through hole, the outer surface of the needle head is sleeved with a guide rod, the top of the guide rod isfixedly connected to the bottom of the connecting block, first sliding blocks are fixedly connected to the outer surfaces of the left end and the right end of the guide rod respectively, and a supporting plate is fixedly connected to the bottom of the guide rod. According to the stabbing-preventing insulin syringe needle, the guide rod, the first sleeve and the first spring are arranged; the needle head sleeves the inner walls of the first sleeve and the guide rod; the needle head is prevented from being exposed and stabbing a user or a patient when not used, and the needle head can be prevented from being polluted by the external environment; the safety coefficient is high, the depth of the needle penetrating into the skin of a patient is limited, the pain of the patient is relieved, thefirst spring rebounds after injection is completed, the needle is automatically pulled out, operation is easy, and the labor intensity of medical staff is relieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a stab-proof insulin needle. Background technique [0002] With the improvement of living standards, more and more middle-aged and elderly people suffer from diabetes. However, insulin is the most common application in the treatment of diabetes. However, most of the existing insulin syringes are simple in structure and inconvenient to operate. The most critical Even if there is no anti-stab function, medical staff often cause needle-stick injuries when injecting insulin into patients. Studies have shown that most medical staff have been stabbed by syringe needles. Whether the patient has other infectious diseases, so if the needle is stabbed after the injection is completed, it will also be a huge harm to the health of the medical staff. At the same time, for some medical staff who have just entered the clinical operation, due to experience Insufficiency It is often difficult to g...
